' brush being portable and so constructed that the dentifrice will not'be spilled or wasted as the vbrush is -jostled about,'but from which` the dentifrice may be applied as desired.

It is another object of thisinventi'on to fprow'ide a tooth brush with a hollow handle 4for containing the dentifrice, and with which means whereby a tooth paste o`r liquid may be forced through the brush back into the space between the bristles, or whereby a powder may be dispensed from the brush handle.

I' attain these trated in the objects by the brush illus- Figure'l is a perspectiveview of my improved toothbrush.

Fig. 3 is a vertical section with the handle removed and showing a collapsible tube secured to the brush.

Referring more particularly to the drawing, my improved brush comprises a hollow handle 7 to which is' securedv a brush back 12' with avalve 15, mounted therein controlling a port- 10 which opens into 'the bristles 11%. l l w y `More specifically, theI brusl comprises a substantially rectangularbrush back 12 of the usual --form having a bore 13 extending longitudinally therethrough, and enlarged at one 'endv 14 forming a seat 9 for a valve 15". The enlarged portion 14 of the bore has one of its walls pierced .by a portl() which `opens into the bristlesll. Mounted withlist inthe bore 14 for reciprocation therein is a piston valve member 15 which is abutted at oneend by a spring' 16. Spring 1,6 1s re- Specication of Letters Patent.

. tained within the bore 14 by a closure screw By 'removing the screw 17, the spring 16 and valve 15 may be removed and' lthe bore in. the brush'cleaned. Bristles 11v secured to the brush back. ,The bristle back" maybe of the rubber set type if desired, that 1s, the/bristles are embedded 'in rubber or some composition.

Secured to the brush back 12 and `prefa erablyintegral therewith is a shank 8 which is flared and has a hollow enlarged extensio'n 21. Shank 8 is reduced in diameter and exteriorly threaded as at.l9, a shoulder at one end, the open end being interiorly threaded for engagement with threads on member/19. The closed end 24 is reduced in diameter 'and exteriorly threaded to engage with threads on'the closure cap 25.

Closed end 24 also has perforations 26 which are for thev purpose i of dispensing tooth To load my improved brush with tooth paste or a liquid, the handle 7 is unscrewed v -from the shank 8. Cap 25 is then unserewed `from handle 7 'and disk-27 is placed over the perforated end 24"'clo'sing the end, and'cap 25 is then replaced. .The collapsible tube 23 loaded with tooth paste or liquid is screwed into place in the shank 8, and the handle 7 is then placed thereover`and secured to the shank. .The brush is now loaded.` and may be carried around in the)v pocket or elsewhere lwithout danger of losing any of the dentifrice. The onlyoutlet of the container 13 against the piston 15 moving it sol that it yoverruns the port allowing the charge of pressed, so that a charge of liquid may be obtainediby inserting the neck 22 into the dentifrice ,liquid collapsing the tube and then permitting it to' expand, and allowing the vacuum in the tube to draw the liquid'.

into the tube. y l

To load the brush with tooth powder, handle 7 is unscrewed from the shank 8, cap

"25 removed .from handle 7 and the disk 27 inserted over the open end in shank 8 as illustrated in Fig. 4. 1n this position of the .disk 27 any dentifrice with which the handle 7 is loaded, will not pass into the brush back.

Cap 25 is now replaced upon the handle 7 and the hollowT compartment in said handle y is loaded with the tooth powder andthen replaced upon shank 8 by screwing it thereon.

When ready to usel the brush upon the teeth, the brush and handle are turned ver-l tically, the end of the' handle struck against theghand or any suitable place, the powder dropping through perforations 26 4filling the pap 25, which serves' as a receiver for the tooth powder, and is so proportioned that. it contains exactly one charge of tooth.

powder for cleaning the teeth. The cap 25 is conveyed to the bristles 11 and the powder then sprinkled over the bristles. AThe cap is lthen replaced on handle 7 closing it against loss of tooth powder, and the brush is ready to'be used on the teeth.,

What I claim is:- In a brush, a handle comprising the com` bination of a handle shank having a bore provided with means for securing a collapsible container thereto, a hollow-handle detachably secured at one end to said shank and provided at the other end with a perfo-l rate closure plate, a closure cap having a recess for containing dentifrice detachably secured to the end .of said handle opposite the said shank, and an imperforate plate ar'- ranged to be detachably disposed between said closure plate and said cap, ,or between as. p'

said handle and said shank to close thebore in said handle.

In witness that I claim the foregoing I have hereunto subscribed my name this twenty-seventh day of February '1915. L
